| 摘 要： | 基于多导体传输线频域方法提出了一种电缆上干扰电压和电流的数值计算方法。实验验证了该方法的有效性,并计算了雷击某500 kV变电站接地网时瞬态地电位差在低压直流电缆上产生的干扰电压和电流,计算结果表明该干扰电压和电流不可忽视。 |
| 关 键 词： | 变电站 瞬态地电位差 傅里叶变换 多导体传输线 |

| Abstract: | This paper presents a numerical method calculating t he interference voltage. The experiment in the paper verifies the validity of the numerical method. The paper calculates the interference voltages and currents in the low-voltage DC cable caused by the ground potential difference that is cau sed when the lightning current strikes directly a 500 kV substation, the calcula ted result shows that the interference voltages and currents couldn't be ignored . |
| Keywords: | substation transient ground potential differe nce Fourier transformation multi conductor transmission lines |
